The. present-invention haswfor its object to produce a device of theclass described which will be simple in construction and capable ofbeing easily installed upon the."

frame of any ordinary conventional corn planter.

A further object of the invention is to produce a lifting device whichwhen disassembled for shipment will occupy but little space and whichmay be readily assembled and installed on the frame of a corn planter.

A further object of the invention is to produce a device of the classdescribed, the parts of which will be simple in construction and easilyassembled or disassembled.

lVith these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawing has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaims may be resorted to when desired.

In the drawing:

Figure 1 is a perspective view showing the parts of the improved device,including the tubular shaft, the limiting collars, the shaft bearings,the lifting arms, and the marker loop, disassembled.

Fig. 2 is a top plan view showing the rearward portion of a planterframe to gi ueanoa fiid ra an 9; iaiai. seriai'no 16,368.?

which the invention has been applied and including; alsothe markers Fig;is -a rear elevation of the same.

Fig. 4 isasideielevationr 1 j 1 Corresponding parts in; the severalfigures o f the drawing. are denoted by like-charactersof reference. c 1j The improved appliance-or planter attachmentincludes-atubular shaft15', bracket 1 membersl-G: having eyes l'l'qthat constitute bear ngs forthe shaft 15, liftingarms A,

one ateachend of the, tubular shaft, limiting eollars 1% whereby theshaft lt'ris re- 7 tamed ln.its. bearings, a. foot .leverB de- 1!tachably connected with the shaft, andga marker loo-p 19 adapted tebeisecured onthe staff 20 of the" conventional marker-which is shown asconsisting of a disk 21 associated with the..marker"staif.

brackets or bearing members are provided with apertures 22 for thepassage of bolts 23 whereby said brackets are secured on the sidemembers 24 of the planter frame from which they extend in a downwarddirection. The foot lever B, which is suitably shaped so as to extendacross the ing 17 of one of said bracket members; the

foot lever B is then placed on the shaft and the latter is now passedthrough the bearing of theother bracketmember. The limiting collars 18are now placed in osition adjacent to the outer faces of the racketmembers 16 and the foot lever may now be properly adjusted and secured.

- Each of the lifting arms A is curved so as to extend beneath themarker stafi 20 and each of said lifting arms has a terminal clamp 28provided with a bolt 29 whereby it may be secured in position. Eachlifting arm has a terminal finger 30 and a lug 31 extendingapproximately at right angles to said finger. Secured on the markerstafi is the loop or keeper 19 which receives the finger 30 of one ofthe lifting arms, the lugtioned and arranged that when properlyassembled and applied to a planter, wlth the loop of the marker staffengaging the,

' shaft 15 in its bearings, thereby lifting the marker clear of theground and holding it in this position until the machine has beenturned. r

The marker, which is connected with the frame of the machine in thecustomary manner by a joint. 32, will now be swung manually or in anyconvenient well known manner into engagement with the lifting arm at theopposite side of the machine.

The improved lifting device for mark ers, as seen from the foregoingdescription, is extremely simple in its construction and is capable ofbeing supplied in disassembled condition, permitting the parts thereofto be packed in small compass. The parts, moreover, are of such a natureas to enable the device to be very easily and quickly R installed on theframe of any ordinary corn planter.-

Copies of this patent may be obtained for Havingthus described theinvention, what is claimed as new is:

1. A lifting device for planter markers, comprising bracket membershaving eyes forming bearings-a shaft supported in said bearings,limiting collars on the shaft adjacent to the bearings, a foot levermounted adjustably on the shaft intermediate the bearings, and liftingarms mounted on the ends of the shaft, in combination with a supportedmarker staff having a loop for engagement with one of the lifting arms.

2. The combination with a planter-frame, of a marker staf'f having aloop secured thereto, bearing members secured on the planter frame, ashaft in said bearing members, a foot lever onthe shaft intermediate thebearing members, and lifting arms mounted on the ends of the shaft, eachof said lifting arms having a terminal finger for engagement with theloop of the marker stafl",'and a lug forming an offset whereby theengagement of the loop on the marker staff with the finger of thelifting arm is limited.

' In testimony whereof I aflix my signature.
